https://en.wikipedia.org/wiki/Floyd_CollinsWilliam Floyd Collins (July 20, 1887 – c. February 13, 1925), better known as Floyd Collins, was an American cave explorer, principally in a region of Central Kentucky that houses hundreds of miles of interconnected caverns within Mammoth Cave National Park, the longest cave system in the world. In the early 20th century, in an era known as the Kentucky Cave Wars,[1] commercial cave owners and explorers in Kentucky entered into a bitter competition to exploit the bounty of caves for commercial profit from tourists, who paid to see the caves. On January 30, 1925, while trying to find a new entrance to Crystal Cave (also known as "Sand Cave" by the media), Collins became trapped in a narrow crawlway, 55 feet (17 m) below ground. The rescue operation to save Collins became a national newspaper sensation and one of the first major news stories to be reported using the new technology of broadcast radio. The rescue attempt grew to become the third-biggest media event between the world wars.[citation needed]
After four days, during which time rescuers were able to bring water and food to Collins, a rock collapse in the cave closed the entrance passageway, stranding him in the cave, except for voice contact, for more than two weeks. Collins died of thirst and hunger compounded by exposure through hypothermia after being isolated for 14 days, just three days before a rescue shaft reached his position. Collins' body would be recovered two months later.
Floyd Collins discovered Crystal Cave in 1917. Crystal Cave is now part of the Flint Ridge Cave System of the Mammoth Cave National Park. Although Collins was an unknown figure in his lifetime, the fame he gained from his death led to him being memorialized on his tombstone as the "Greatest Cave Explorer Ever Known".
